T ree cases of sarcomas of theJ we femur were treated by region-a?ir? ation with overdosage of me-chlorethamine for 3 weeks and there-after a high amputation was done,and the distal leg was replantedwith the length that the anklewould act as a knee joint and thefoot pointing backword. Follow-upfor 1 -5 years discovered no me-tastasie of the tumor and the artifi-cial limb showed a better function.
Objective To study the effect of vein-occlusion on the replanted limb survival in SD rats at different stages. Methods Twenty-five adultSD rats were randomly divided into 5 groups according to the time of the femoral vein occlusion after the replanted limbs:2- ,3- ，4 -，6-，and 8- day groups. The limbs were observed through naked eye, measurement of dermal temperature and angiography. Results No formation of collateral veinlet was found, and necrosis wasseen in the replanted limbs of 2- , 3- day groups. Reflux-vein was gradually increased in the replanted limbs of 4，6，and 8 day groups. Angiographic score of capillary density and dermal temperaturein the thigh muscles were greater in groups 4-，6-，and 8- day than in groups 2 and 3 day. Conclusion Within 2 and 3 days，the replanted limbs of SD rats will necrose because of vein-occlusion; and 4 days later the replanted limbs can survive depending on the reflux-vein of new collateral veinlet.
Objective To evaluate lumbar laminotomy and replantation in prevention of spinal unstability and peridural adhesion after laminectomy.Methods From February 1995 to March 2001,a total of 169 patients(96 males, 73 females,aged 22-63) with lesions in the lumbar vertebral canals underwent surgery, in which the lesions were removed afterlaminectormy and then the excised laminae were replanted. Results The follow-up for 5-9 years showed that all the patients had no complications after the lesions were removed. According to the evaluation criteria formulated by WANG Yongti，81 patients had an excellent result, 67 had a good result, 19 had a fair result, and2 had a poor result. 87.6% of the patients obtained quite satisfactory results.The X-ray films demonstrated that the replanted laminae obtained bony healing and the spine was stable. The CT scanning demonstratedthat the canals were enlarged with a smooth and glossy interior. Conclusion Lumbar laminotomy and replantation is reasonable in design and convenient in performance, which can be promoted as a basic operation in spinal surgery.
OBJECTIVE: To discuss the indication of replantation of destructive amputation of multiple fingers for improvement of the function of injured fingers. METHODS: From February 1996 to August 1999, 23 amputated fingers in 8 cases were shortened and replanted. The crushed digital bones were fixed by Kirschner wires, flexor tendons repaired by Kessler suture technique, and digital extensor tendons repaired by mattress suture. The arteries and veins were anastomosed in each finger at the ratio of 1 to 2 or 2 to 3. The defect of blood vessels was repaired by free graft of autologous veins in 5 fingers. All of the cases were followed up for 10 to 18 months, and clinical evaluation was performed. RESULTS: All replanted fingers survived in the 8 cases, with good sensation, two point discrimination of 6 to 12 mm, and satisfied function, such as pinching, grasping and hooking. The fingers were shortened for 2.6 cm in average, ranging from 2.2 cm to 4.0 cm. CONCLUSION: Multiple digits replantation by shortening fingers is beneficial to functional restoration of segmental destructive fingers.
Objective To explore the effectiveness of arterial crisis after replantation of limb treated by ultrasound guided Fogarty balloon catheter. Methods Between January 2012 and July 2016, 27 patients suffered from arterial crisis after replantation of limb were treated with ultrasound guided Fogarty balloon catheter combined with thrombolytic anticoagulant. There were 18 males and 9 females with the age of 19-51 years (mean, 32 years). The limb mutilation position was at knee joint in 3 cases, lower limb in 9 cases, ankle joint in 6 cases, elbow joint in 2 cases, forearm in 4 cases, and wrist joint in 3 cases. The arterial crisis happened at 2.5-18 hours (mean, 7.5 hours) after limb replantation surgery. Color doppler ultrasonography was used to diagnose the arterial thrombosis, finally the anastomotic thrombosis were found in 16 cases, non-anastomotic thrombosis in 7 cases, and combined thrombosis in 4 cases. All the thrombosis were deteced in the arteries with the length of 0.8-3.9 cm. Results No complication such as vascular perforation, rupture, air embolism, thromboembolism, wound infection, or sepsis happened after operation. Arterial crisis occurred again in 3 cases at 1.5-13.5 hours after limb replantation and treated by arterial exploration, 1 case was treated successfully; 2 cases had arterial occlusion and partial necrosis of limb, and got amputation treatment at last. The rest 24 cases survived with the incision healing by first stage. In the 24 cases, 1 case suffered from acute myonephropathic metabolic syndrome and corrected after hemodialysis; 1 case suffered from acute liver functional damage and corrected by comprehensive treatment of internal medicine. The 24 patients were followed up 7-38 months (mean, 11 months). At last follow-up, blood supply of the limb was good with normal skin temperature and improved sense of feeling, activity, and swelling. According to Chinese Medical Association of hand surgery to the upper extremity function assessment standard, the results were excellent in 12 cases, good in 8 cases, and fair in 4 cases with an excellent and good rate of 83.3%. Conclusion Ultrasound guided Fogarty balloon catheter treatment of posterior replantation of arterial crisis can accurately locate the thrombosis, get the thrombus fast and invasive minimally to avoid the blind and repeated thrombectomy, and obtain certain effectiveness.

The replantation of amputated finger (or limb) and the reconstruction of the thumb and fingers started in 1960s in China. With the development of microsurgical techniques, both finger replantation and reconstruction achieved worldwide significant success. And now it is not the survival rate but the function of replanted finger that attracted more attention. Moreover, the breakthrough of particular type of digital replantation has broadened its indications. In terms of reconstruction, not only that a great deal of experiences in dealing with different types of thumb defects was accumulated, but also more micro-surgeons focus on minimal invasion and reducing the damage to the donor area.
ObjectiveTo review the experience of the surgical treatment of child patients with anomalous left coronary artery from the pulmonary artery (ALCAPA). MethodsWe retrospectively analyzed the clinical data of 56 children patients with ALCAPA underwent coronary re-implantation in our hospital from April 2004 through February 2015. There were 35 males and 21 females at mean age of 25.5 (7.3-60.0) months. Nineteen patients (33.9%) were less than 1 year of age. The mean weight was 11.8 (7.8-19.8) kg. ResultsThere was one death in-hospital. The mean cardiopulmonary bypass time and cross-clamp time was 131.8± 61.2 min and 83.4± 32.1min, respectively. The mean mechanical ventilation time and intensive care unit time was 12.5 (6.5-43.8) h and 49.0 (21.0-116.0) h, respectively. Three patients underwent extracorporeal membrane oxygenation (ECMO) support and weaned off successfully. The mean postoperative left ventricular ejection fraction (LVEF, 63.4%± 15.8% vs. 50.6%± 18.7%) and left ventricular end diastolic diameter (LVEDD, 36.4± 32.5 mm vs. 42.3± 7.4 mm) significantly improved compared postoperative (P < 0.05). The mitral regurgitation (MR) distribution in the 15 patients underwent mitral valve repair was:moderate in 2 patients, mild in 8 patients, trivial in 2 patients and none in 3 patients. The MR in the other 41 patients improved or did not change. The survivors completed the follow-up for a mean time of 45.4± 23.6 months. During the follow-up period, one patient died due to noncardiac reason. No patient required reoperation or readmission. All the patients survived with New York Heart Association heart function classⅠor classⅡ. At the latest echocardiography, the mean LVEF (62.8%± 5.0%) significantly improved compared with the LVEF of discharge. The MR distribution was moderate in 6 patients, mild in 24 patients, trivial in 4 patients and none in 21 patients. ConclusionThe coronary re-implantation has a satisfactory mid-term result for patients with ALCAPA. Mitral valve repair is recommended for the patients with severe regurgitation and evident ischemic lesions of the papillary muscles.
